This paper provides an in-depth description of our large-scale web search engine - the first such detailed public description we know of to date. Furthermore, due to rapid advance in technology and web proliferation, creating a web search engine today is very different from 3 years ago. Despite the importance of large-scale search engines on the web, very little academic research has been done on them. They answer tens of millions of queries every day. Search engines index tens to hundreds of millions of web pages involving a comparable number of distinct terms. The prototype with a full text and hyperlink database of at least 24 million pages is available at To engineer a search engine is a challenging task. Google is designed to crawl and index the Web efficiently and produce much more satisfying search results than existing systems. In this paper, we present Google, a prototype of a large-scale search engine which makes heavy use of the structure present in hypertext. Provide a permanent and basic knowledge of signals, data, information, However, just at a time in which (almost) everyone has the possibility ofĪccessing an practically unlimited amount of information, it is necessary to Up to 50% of product costs and more than 50% of indirect In the industry 75% of employees no longer work with material, but with Information obtains an increasingly important position. The Internet penetrates our everyday life with a nearly infinite abundance of Gigabits per second, the post-modern information society becomes reality. All these elements set the foundation for a worldĬomputer Science and Information Technology are continually breakingĭown currently putative boundaries. Possibilities of information and communication (IaC) have increased an Technology and millions of cross-linked computers worldwide, the technical Due to satellite technology, optical fibre The society in which we live is becoming increasingly Multimedia – distributable over world-wide networks – a completely new With the entrance into the digital world of information processing with Interchanges, become increasingly complicated and abstract. In each case the information transmitted, and the systems used for these World, only consider the transmission of hereditary information (geneticīlueprints) or the inter-communication of living beings. Information and Communication is not only important in computer science,īut is also of central importance to the existence of (civilised) life in our The following Information and Communication Theory Of the basic principles involved is necessary. Types of information and information processing, a thorough understanding Multimedia Systems are Information Systems (IS) in which all kinds ofĪuditory and visual information are offered.
